What is the phenomenon that occurs when excited gaseous elements emit only a few colored lines?
A) Planck's constant

C) line spectrum
D) quantum theory
E) electromagnetic spectrum

Question

Quizplus · Accepted Answer

The phenomenon described is known as a line spectrum, which occurs when excited gaseous elements emit only a few specific colors or wavelengths of light. This is due to the quantized nature of energy levels in atoms, which only allow for certain transitions between electron orbitals and result in the emission of discrete spectral lines.
